A multi-fuel stove 1 supplies both secondary air 11, to keep the window 12 clean, and tertiary air 26, to increase flame height and efficiency, from a combined inlet chamber 36 fed by vents 38. Airflow into the secondary conduit (72, fig. 3) and tertiary conduit 40 is independently controlled via knobs 52 and 58 (fig. 4) on the front of the stove, improving access without compromising appearance. The secondary conduit's tapered exit (70, fig. 3) prevents smoke entering the room via inlet vents 38, as does the tertiary conduit's upwards inclination 40. |
